Par EndFedz® Antennas
Par EndFedz® Antennas are End Fed Half Wave (EFHW) antennas with the match box coax connection at the end of the wire, for convenient and quick stealth portable operations. These single-band and multi-band antennas can be mounted horizontally, vertically, or as a sloper. No ground plane or counterpoise is needed so portable operation could not be easier. Simply hang the far end from a tree limb or send the wire out a hotel room window or balcony. You can use a telescoping fiberglass mast to get the antenna really high in the air and the supplied end insulators the installation easy. Stealth operation in CC&R and HOA antenna restricted locations is simplified. Their all-black construction makes them difficult to see. Each Par EndFedz® features a UV-resistant black ABS plastic housing with a support rope attachment hole that encloses a matching network to allow the antenna to be fed with standard 50 ohm coaxial cable with a PL-259 (UHF male). All hardware is stainless steel and the SO-239 (UHF female) connector is silver plated and has a PTFE dielectric. The antenna wires are either 18 or 26 AWG stranded Copperweld® with 200 pound breaking strength and a tough, 100% UV stable black polyethylene jacket. One end of the antenna wire has a #10 solder lug making attachment to the matching network feedpoint simple and easily replaceable, if necessary. Standard single and multi-band versions handle 100 or 200 watts and higher power versions handle 300 watts. Lightweight QRP PolyStealth models handle 25 watts and are ideal for portable operation because they are lightweight; the MKII model weighs only 8 ounces and the Trail Friendly model weighs only 3.5 oz. Par EndFedz® Antennas require no counterpoise or extra conductors. The EF-ALLBAND-KW model, about 133 ft. in length, covers eight bands, 80 through 10 meters. The ALLBANDKWJR is 74 ft. in length and operates on five bands, 80-10 meters. The 64 ft. EF-40-10-KW operates on four bands. All three models handle up to 1000 watts SSB/CW and 250 watts AM/Digital Modes. The need for an external tuner may vary based on the antenna model selected and the desired operating band. The manufacturer refers to these antennas as "End-Fed Dipoles" based upon the assertion that a "half-wave radiator is a dipole." This is a variant of the classic definition of a dipole which is a center-fed antenna with two radiating legs running in opposite directions from the feed point. Additional claims about the EFHW state that end feeding a half-wave "can energize the radiator 'nearly' as well as a center-fed." Recent anecdotal measurements indicate that the EFHW radiates about 70% as well as a traditional center-fed dipole. More information is available at each Par EndFedz® model listed below.

Comet GI190 Series VHF/UHF Ground Independent Mobile Vertical Antennas
Comet VHF/UHF Ground Independent Mobile Vertical Antennas are dual-band mobile antennas designed for installation in places where traditional ground plane antennas won't work. The GI190 requires no ground plane, meaning installation on vehicles such as RV's boats, golf carts, ATV's and motorcycles is now possible with the GI190 antennas. At a mere 28 in. long and available with both UHF or NMO connectors, the GI190 antennas provide 2.15 dBi on VHF and 5.0 dBi on UHF. With a maximum power rating of 70W, the GI190 is a perfect match for most of today's mobile radios.

Diex Antennas Two-Band Trap Shortened Rigid Rotatable Dipoles
Diex Antennas Two-Band Trap Shortened Rigid Rotatable Dipoles offer high performance multi-band HF operations, and they are an excellent choice where there's not enough space for a full-size dipole or Yagi. Crafted with precision in Brazil using quality materials, these aluminum tubing antennas are designed to withstand tough environments assuring long-lasting, exceptional performance. They are packed partially assembled, saving valuable time and effort. Typically mounted on a rotating mast, these unique multi-band HF antennas provide high-band directionality depending upon installed height above ground. Given the nature of shortened low-band antennas with limited SWR bandwidth, these antennas feature the flexibility of physical adjustment to set the lowest SWR to a specific frequency. DIEX Antennas Two-Band Trap Shortened Rigid Rotatable Dipoles power handling is 1500W PEP SSB, which is further limited if using an antenna tuner. NOTE: Diex Antennas recommends that a directional HF antenna should be mounted on a tower at a minimum height of 33 to 50 ft. (10 - 15 meters) above ground level and must be installed in the clear, away from power lines, trees, buildings or other towers and antennas.

Hamplus HR-100L Rotator Controller with PC Interface
The Hamplus HR-100L Rotator Controller was developed to offer an inexpensive solution for manual and PC control of all models of rotators that use a 24 volt DC motor and a position indicating potentiometer. It is specifically designed to connect to any existing Yaesu rotator and control cable. This compact desktop unit features a black front panel with four illuminated directional memory buttons, a red three-digit LCD display to indicate rotator azimuth, an azimuth selection encoder knob, two buttons for CW and CCW advance, a special +180° button for an easy Long Path selection, two LEDs to indicate the ends of rotation and one LED in the LCD to indicate overlap. The HR-100L also has an RS-232 Serial port for PC control with any third party software, such as rig control and logging software, which supports the Yaesu protocol for rotators. A rear panel switch selects either 120VAC or 240VAC input voltage and the Yaesu style 6-pin connector is ready for the control cable to any Yaesu or 24VDC rotator, including G-450DC, G-800DXA, G-1000DXA and G-2800DXA, as well as other brands that use a similar configuration. With dimensions (WHD) of 12.2 x 5.9 x 13.0 in (310 x 150 x 330mm), the Hamplus HR-100L Rotator Controller is simple to set up and amazingly easy to use with your rotator! DX Engineering Yaesu Rotator Cable Assemblies are directly compatible, premade in lengths of 10, 50, 75, 100, 125, 150, 200 and 250 ft.

4O3A A50 Antenna/Load Switches
4O3A A50 Antenna/Load Switches serve as 50-ohm loads for open ports on the HFC4500 combiner or other multiplexer, preventing tuning degradation. Applying 12V power connects the input to the combiner's output, linking it to the corresponding combiner or filter. A typical setup switches a filter or a combiner to a monoband antenna. When the A50 is not powered, the switch defaults to a 50-ohm termination for the input and the antenna output is open. NOTE: The A50 is NOT an A/B switch. The manufacturer's label of "A/B Switch" is a product grouping, NOT an indication of the function of this product. The LOAD resistor is internal, so one of three connectors is unnecessary, which leaves an open hole in the chassis, a "normal feature" of the A50.
